Pre-tensioning method pre-stressed pile downward pressing auxiliary device and construction method
The invention relates to the technical field of pre-stressed pile pressing, in particular to a pre-tensioning method pre-stressed pile pressing auxiliary device and a construction method.According to the pressing auxiliary device, a top pile opening of a pre-stressed pile is fixed, during construction, a pile feeder is placed on a supporting plate, the bottom end of the pile feeder is limited through an edge plate on the upper side of the supporting plate, and the bottom end of the pile feeder is fixed; the pile pressing effect is prevented from being influenced by horizontal movement of the pile feeder; the supporting piece is supported in the prestressed pile, so that the supporting plate firmly covers the pile opening position of the prestressed pile, and horizontal displacement is avoided when the downward pressing auxiliary device presses the pile; the horizontal position of the pile feeder is limited through the lifting hook, and meanwhile the downward pressing auxiliary device can be conveniently pulled out of the soil body through the lifting hook after pile pressing.
本发明涉及预应力桩下压技术领域，具体是一种先张法预应力桩下压辅助装置及施工方法，本发明的下压辅助装置将预应力桩的顶部桩口固定，施工时，将送桩器放置在托板上即可，托板上侧的边缘板将送桩器的底端限位，避免送桩器水平移动影响压桩效果；通过支撑件支撑在预应力桩的内部，使托板牢固地盖在预应力桩的桩口位置，避免下压辅助装置压桩时发生水平位移；通过吊钩限定送桩器的水平位置，同时方便压桩后通过吊钩将下压辅助装置拔出土体。
